Definitions

  • the invention relates to a vehicle with an internal combustion engine according to the preamble of patent claim 1.
  • the invention has for its object to develop a generic vehicle in such a way that even very powerful engines can be used without the loads on the areas of the vehicle adjacent to the engine compartment and the outside world increasing unduly.
  • the protective cladding on a protruding component surrounding the engine such as the axle support, the so-called “integral support”, close to the engine makes noise, waste heat and vibration excitations that result from engine operation. ren, comprehensively and without significant consequences for the engine, auxiliary units and other supply-related components. Due to the proximity of the engine, the spread of noise and waste heat is inhibited at an early stage. The outside world will, if at all, notice a slight increase in pollution. Powerful motors can thus be used without having to put up with harmful consequences.
  • the protective cladding of the axle support body even lightweight materials such as aluminum, which are sensitive to high temperatures, can be produced without any problems.
  • the invention is not limited to the said integral support alone. As is known, there are also vehicles without integral beams in which cross-beams take over its function. In this respect, the cladding of this cross member according to the invention is also conceivable.
  • FIG. 1 is a plan view of an axle carrier according to the invention with fully clad longitudinal sides
  • Fig. 2 is a perspective view of a portion of the axle carrier according to the invention with a partial cladding of the long sides of the axle carrier.
  • axle support 1 shows an axle support 1 of a vehicle with an internal combustion engine, which is mounted thereon at points on the longitudinal sides 3 of the axle support 1 designed as engine mounts 2.
  • the axle support 1 itself is made of steel or aluminum and has a protective covering 5 on its upper side 4.
  • the protective cladding is screwed to the axle support 1 at fastening points 6.
  • the covering 5 can also be glued or clipped onto the axle support 1.
  • the two longitudinal sides 3 of the axle support 1, which extend parallel to the longitudinal axis 7 of the vehicle, are completely covered by means of the covering 5, with the exception of the attachment points 8 for attachment to a side member of the vehicle and the engine mount 2.
  • the large number of fastening points to be provided for individual claddings is eliminated, which on the one hand considerably simplifies the design of the axle support 1 and the cladding 5 and their assembly.
  • a further simplification of the solution is shown that the two cladding sections 5 of the long sides 3 can be connected to one another in one piece, so that they form a single component, the connecting sections the cross bridges 9 of the Axle beam 1, which connect its long sides 3 to each other, completely cover. This means that a minimum number of cladding parts with a maximum shielding effect is achieved.
  • the cladding 5 is skin-like in accordance with the contour of the upper side 4 of the axle support 1 and is space-saving.
  • axle support 1 In order to avoid an uncontrolled outflow of the air heated up by the engine waste heat to the outside, in particular to areas of the vehicle relevant to engine waste heat, it is particularly advantageous that all openings and openings of the axle support 1 are covered in a soundproof and heat-resistant manner. These are in detail the wishbone opening 10 and the spring link opening 11 of the axle beam 1 and an intermediate space 12 between the side member of the vehicle, to which the axle beam 1 is attached, and the axle beam 1. Furthermore, it is particularly important to cover a bearing point 13 of the Axle carrier 1 for an axle stabilizer.
  • the protective covering 5 advantageously consists of a material with special heat-insulating properties.
  • the heat-insulating material of the cladding 5 is also equipped with sound-insulating properties, so that multifunctional properties are anchored in a single cladding part to save components and space.
  • the material must in principle be hard enough and designed with low thermal conductivity and a large heat absorption capacity in order to be able to provide adequate thermal insulation.
  • it must be so soft that sound insulation is guaranteed.
  • the panel 5 must not rattle against the axle support 1 when the vehicle is in operation.
  • thermoplastic materials preferably polyamide (for example PA6 / X-HI, EGR, 12-002N according to ISO 1874/1) or polyurethane or in an elastomer-modified two-component system with polyurethane.
  • the material of the cladding 5 can also consist of two interconnected plastics, superimposed plastic layers or plastic parts, one plastic having the sound-insulating properties and the other plastic having the heat-insulating properties. It is important to ensure that the plastic with the heat-insulating properties is arranged above the plastic with the sound-insulating properties so that the properties come into their own.
  • the different materials can be spatially connected to one another within a single cladding part or concentrated on separate cladding parts.
  • the cladding 5 is an independent component which, with the exception of the fastening points 6 of the cladding 5 on the axle support 1, has an air gap between it 14 is spaced.
  • the width of the air gap 14 is preferably in the range of approximately 2 mm. If the installation space allows, it is conceivable to construct it with air chambers on the top of the cladding 5 in order to obtain a further increase in thermal insulation and sound insulation.
  • the cladding according to the invention consisting of the above-mentioned plastic due to its relatively smooth surface in the function as abrasion protection against the roughness and sharpness of the axle beam 1 compared to soft material hoses and lines running in or along the engine compartment, which, for example, carry hydraulic oil or brake fluid or form electrical supply lines.
  • FIG. 2 shows a partial cladding 5 of the axle carrier 1.
  • This partial cladding can be used, for example, in engines with a lower power output, since there only a covering of the essential areas relevant to heat and sound insulation of the axle support 1 is of grade.
  • 2 shows the air gap 14 at the fastening points 8 particularly clearly.
  • the covering 5 is attached to the axle support 1 both in the variant according to FIG. 1 and in the embodiment according to FIG. 2 before the motor is mounted on the axle support 1. This can prove difficult for the subsequent assembly of the engine due to the lack of it Accessibility Make the screw and / or clamp connections functionally effective.
  • the covering 5 is provided with diametrical slots 15 on a circular surface at locations of covered openings 10 and 11 of the axle support 1.
  • the resulting slit blades 16 are resilient, so that the cladding 5 for assembly with an assembly plant Stuff can be easily pierced and automatically goes into the closed position after assembly and retraction of the tool without losing its functionality in terms of thermal insulation and sound insulation.
  • This restoring effect can be achieved solely by the constructive measure of forming a slotted dome-shaped elevation 17 over the circular area.
  • the diametrical slitting ensures the same spring strengths of the slotted blades 16, so that there is no canting or jamming when the tool is being carried to the assembly site and away from the assembly site.
  • two smaller elevations 17 arranged side by side can also be formed in a practical manner.
